Metastatic Pulmonary Calcification in Multiple Myeloma in a 45-Year-Old Man

الملخص EN

Metastatic calcification has been associated with multiple-myeloma-induced hypercalcemia.

Despite of a relatively high prevalence of metastatic pulmonary calcification in patients with multiple myeloma, only a few cases have been clinically and radiologically detected.

A 45-year-old Hispanic male presented to the Emergency Department with complaint of worsening weakness and myalgia.

Laboratory findings revealed renal insufficiency and hypercalcemia.

CT scan of chest revealed calcified pleural and pulmonary nodule.

Technetium (Tc) 99 bone scan revealed diffuse activity in the pulmonary parenchyma consistent with metastatic pulmonary calcification.

Metastatic pulmonary calcification, despite its high prevalence, remains undetected.

This is, in part, due to its radiographic characteristic properties that evade detection by routine imaging studies.

We present a case of a metastatic pulmonary calcification in a patient diagnosed with multiple myeloma and chronic kidney disease, as well as a brief literature review including clinical findings and treatment options.
